Omaha Public Power District 1623 HARNEY a OMAHA, NEBRASKA 68102 e TELEPHONE S36 4000 AREA CODE 402 July 22, 1982 LIC-82-266 Mr. H. R. Denton, Director U. S. Nuclear Regulatory Commission Office of Nuclear Reactor Regulation Washington, D.C. 20555

Reference:

Docket No. 50-285

Dear Mr. Denton:

Fort Calhoun Station Unit No.1 Updated Safety Analysis Report As required by 10 CFR 50.71(e), thirteen (13) controlled copies (numbered 1 through 13) of the " Fort Calhoun Station Unit No.1 Updated Safety Analysis Report" have been forwarded under separate cover. The update was performed to incorporate all plant modifications made to the Fort Calhoun Station and to reflect information and analyses submitted to the Commission since the previous submittal of the Final Safety Analysis Report (FSAR) with amendments and up to January 22, 1982. All changes to the original FSAR received a rigorous technical review, as well as a formal final review and approval oy the District's Safety Audit and Review Committee and Plant Review Committee. Based upon this review and approval process, Omaha Public Power District believes the Updated Safety Analysis Report accurately reflects the design of the Fort Calhoun Station as it existed January 22, 1982.

Attachment 1 identifies those plant changes made pursuant to 10 CFR 50.59, but not previously reported to the Commission. The majority of these changes (19 of 26) were either completed recently (i.e. , the last six months) or were lacking final documentation for closecut and, thus, had not yet been reported. These 19 will be reported in the July Monthly Operating Report. The remaining 7 changes were relatively minor modifications which were not originally considered under the scope of 10 CFR 50.59, but are included on Attachment 1, since they are reflected in
